Abstract:
A
landslide is a downslope gravitational movement of rock, earth, or
antificial fill. The movement may be a slide, flow, or fall, acting singly or
together (Simonett, 1968). Landslide may be induced by natural agencies
such
as
heavy
such
rain
or
earthquake or it may be caused by human
interference with slope stability (Whittow, 1984). Among the natural
hazards,
as
earthquakes, seismic sea waves, volcanic eruptions,
tropical cyclones, monsoon storms, tornadoes, thunderstorms, sea fogs,
sea ice, and iceberg drift, landslides are least documented and researched.
This could be because they are restricted to small areas or because no
adequate statistics are available (WMNH, 1988; Fig. 1). However, the
extreme
rainfall
intensities,
thunder and lightning, and downslope
movement of rocks, debris, or earth associated with landslides can
damage the natural environment as well as destroy life and property
within a short period of time.
